LSU head coach Ed Orgeron announced linebacker K'Lavon Chaisson will miss the remainder of the 2018 season after suffering a torn ACL in the Tigers' season-opening win over Miami.
Ross Dellinger of Sports Illustrated reported the news.
Chaisson recorded five tackles and a sack in LSU's dominant 33-17 win.
"I feel bad for him," LSU coach Ed Orgeron told reporters. "He's a great young man. He's going to get through this and will have a great career down the road."
The sophomore tweeted out his thanks to everyone after Orgeron announced the injury.
"Thanks to everyone who sent out thoughts and prayers! It's a tough thing to handle but I'm surely not alone. I ask that you keep sending blessings and prayers my way as we trust in the Lord and his plan. See y'all next season!" Chaisson tweeted.
Chaisson recorded 27 tackles and two sacks as a freshman. He was expected to be a breakout star for an LSU defense that looked strong in the season opener, forcing two turnovers and holding Miami to three points in the first three quarters.
Losing Chaisson will increase backup Andre Anthony's role going forward. Anthony, a sophomore, has battled foot injuries throughout his collegiate career and played in his first game Sunday.
